Hi,
Now if you search GitHub topics like this one: https://github.com/topics/kerbal-space-program
You should see something like this.
That's because my PR was accepted: https://github.com/github/explore/pull/100
But I don't feel like my proposal is complete without asking the community around about feedback.
Any suggestions? You can make your own PR, but please: don't overwhelm maintainers from GH.
If you are maintainer of KSP add-on, you can add topics in your repository.
Best regards!
